VAPORIZER FOR INTERNAI'L-COIYIBUSTION ENGINES.

To all who/m, it may concern:

Be it known that I, KNUT JONAS gELiAs HnssELMAN, a citizen of theKingdom of Sweden, residing at Saltsj Storingen, Stockholm, Sweden, haveinvented new and useful Improvements in Vaporizers torlnternal-Combustion Engines, of which the following is a specification.

This invention relates to an improvement in the vapori-zers described inmy United States Patent No. 910534.

The invention will be fully understood from the following descriptionand claims when the same are read in connection with the drawings,accompanying and forming part of this specification, in which:

Figure 1 is a longitudinal section of my improved vaporizer. Fig. 2 is aSide elevation of the same.l I

Similar numerals of reference designate corresponding parts in bothvviews of the drawings.

TheA fuel or oil passes through the channel 2 into the supply channel 3from which it flows through the narrow ports 4 of the vaporizer body linto pockets 5 provided in the vaporizer body. lVhen the valve 6 is openthe oil is carried by the air pressure through the channelA T and 4intothe cylinder.

In furtherance of my present invention each connecting channel or port 4is formed with two enlarged portions 8. The number of such portions is,however, arbitrary. The portion of each port 4 connecting the twoenlarged portions 8 with each other should be wider than the portion ofsame port connecting the annular oil supply channel 3 and the enlargedportion 8 nearest to said channel 3 in order that the oil may pass at alower speed between the two enlarged channel poi-tions than between thechannel 3 and' the enlarged channel portion nearest thereto. In usingfor instance three enlarged por- -tions in eaclrconnecting port 4 theportion between/the last two enlarged port portions is made wider thanbetween the first two enlarged port portions and so on. The portions ofthe ports 4 forming connecting passages may, as is shown in the drawing,be displaced in relation to cach other so that the path of the oilbecomes curved whereby the whirling motions of the oil will beincreased. By suitable choice oi" the number and size of the enlargedport portions and of the cross sectional area of the port portionsbetween the said enlarged portions one may reduce the speed of the oilin anydesired degree, s0 that .the oil settles quietly in the pockets 5and is thereupon carried by the air through the channels 7 in a reliablemanner when the valve 6 is opened.

The vaporizers of my said Patent No. 910,534, dated January 26, 1909have proved satisfactory in function when placed vin vertical orapproximately vertical position. bntthey are` not reliable when .placedin norizontal or approximately horizontal position. This is due to thefact that oil introduced into the annular supply channel 3 tends onaccount of gravity to occupy the lowermost portion of said channel, andthat to attain a uniform distribution of oil around the vaporizer bodyit is necessary to make the connecting ports very narrow in order toobtain in the same a resistance that is suicient to compel the oil to`distribute itself uniformly in all of the connecting ports. The oilifiii'st, however, pass through the* connecting ports with greatrapidity. T his rapidity prevents the oil from settling quietly in theockets, and it is therefore necessary to re uce the same to a materialextent. To this end the connecting ports between tlie oil supply channeland the pockets are as described formed with one, two or more enlargedportions in which the rapidity of motion of the oil will be reduced byfriction and whirling motion'so that the oil can settle quietly in thesaid pockets.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A vaporizer of the type described for internal-combustion engines`comprising a body having-an oil-'supply channel and oilreceiving meansspaced from Said channel' and also having connecting channels extendingdirectly between the oil-supply channel,

and the oil-receiving means; each of said channels being provided with acomparatively large portion adjacent und connected with theoil-receiving means land a contracted portion between said large portionand the oil-supply channel.' l.

2, A vaporizer of the type described for internal combustion engines,comprising a ,body having an oil-supply channel and oilreceiving meansspaced from said channel and also having between said oil-supply channeland oil-receiving means, connecting channels each of which is providedwith space 7 @nlm-gm por ions nous bemg connect 5 tion 'with the, TT-su'v v. in tes'mmony txti a my inviami-icm have signed my name in.
